7. General Specifications Power Requirement Regulated Voltage: Maximum Current for power supply: +12 to +24 VDC 2.5 A Operating Temperature Electronic components used in the DMX-K-DRV have maximum ambient operating temperature of 85 degree Celsius. DMX-K-DRV electronics are potted with heat-conductive compound to the housing to evenly distribute the heat and reduce any hot spots in the driver. Housing also has integrated fins to better dissipate the heat. DMX-K-DRV has internal temperature sensor which protects the driver incase of overheat. At temperatures above 75 degrees Celsius, the driver shuts off automatically to protect the electronics from being damaged. Please refer to the temperature sensing section for details. DMX-K-DRV should be mounted securely to a metallic bracket that can also act as a heat-sink. During operation, the step motor section typically becomes hotter than the driver section. Having the step motor mounted to a heat sink will help dissipate the heat generated by the step motor. DMX-K-DRV mounting orientation should be such that the fins are oriented vertically for better convection and heat dissipation.

DMX-K-DRV-23 Interface Circuit

Pulse/Dir (CW/CCW) Inputs DMX-K-DRV supports both one-clock (PULSE/DIR) or two-clock (CW/CCW) inputs. One-clock uses PUL signal as pulse train input position control and DIR signal as direction input signal for direction control. Two-clock uses CW as clockwise pulse input and CCW as counter clockwise pulse input for position control. Depending on the direction polarity setting, actual direction of the rotation can be configured for the application. Pulse/Dir (CW/CCW) inputs are opto-isolated differential inputs with 470 Ohm resistor:

Example of Wiring using Differential Output Example of Wiring using Open Collector Output

Enable Input Enable Input is an opto-isolated input with a 470 Ohm resistor and Diode. Example Wiring of Enable Input Microstep DMX-K-DRV comes with Bipolar step motor and has the following configurable microstep setting ranges: Full Step, Half Step, Quarter Step, 1/16 Step. Current Control DMX-K-DRV has configurable current setting from 100mA to 2.5A peak current. Driver current is set to Run Current when the pulse input is detected and remains in run current while the pulse input is detected. Idle Current is used when the pulse input is idle for the duration set by the Idle Time. Run Current and the Idle Current should not go over the maximum rated current for each motor size. Use the chart below as a reference on maximum rated current setting. Product Maximum Peak Rated Driver Current Setting (Amp) DMX-K-DRV-11-1 1.2 DMX-K-DRV-11-2 1.2 DMX-K-DRV-11-3 1.2 DMX-K-DRV-17-2 1.7 DMX-K-DRV-17-3 2.0 DMX-K-DRV-23-2 2.5 DMX-K-DRV-23-3 2.5

Over Temperature Alarm DMX-K-DRV has a temperature sensor to detect over heating of the driver. Temperature sensing is done only when the driver is enabled. When the temperature goes over the overtemperature alarm value 70 degrees Celsius, the Alarm Output is turned on. If the temperature goes below the 68 degrees Celsius, the alarm output is turned off. If the temperature goes over 75 degrees Celsius, the driver is automatically turned off and remained off until the temperature goes below the 68 degrees Celsius. Alarm output is an opto-isolated output with 100 Ohm resistor. Example Wiring of Alarm Output

8. Driver Configuration Following are DMX-K-DRV parameters that can be configured: 1) Microstep Setting: Full, Half (1/2), Quarter (1/4), Sixteen(1/16) 2) Run Current: 100mA to 2.5A peak current 3) Idle Current: 100mA to 2.5A peak current 4) Idle Time: 100 msec to 10 sec 5) Direction Polarity 6) One-clock or Two-clock mode DMX-K-DRV uses patent-pending Dynamic Configuration Method to read and write the driver parameters using the control signals (Pulse, Dir, Enable, and Alarm) of the driver. Dynamic Configuration eliminates the need for jumpers, switches, resistors, potentiometers and communication port for reading and setting the driver parameters. This results in simple and cost-effective device.
